Properties of Coconut Fibres Reinforced Cashew Nut Shell Resin (Published)

Cashew Nut Shell Resin (CNSR) was reinforced with chemically modified coconut fibres.  Modified fibres were treated with alkali solutions of NaOH (10%) and bleached with sodium hypochlorite. The bio-composites were fabricated using hand lay-up technique. The tensile tests showed that the mechanical properties (modulus, strength, and elongation at break for the tensile, compressive and bending) of composite improved significantly when compared with the fibre. The tensile strength improved by more than 200% while the Young modulus increased by over 305% in comparison with the fibre. Strain at break decreased by 61.76%. The compressive properties show that the strength increases by 169% while the Young Modulus increases by 53.05% and the compressive strain at break increases by 122.86%. SEM failure mode of all testing were observed to the same. Tensile failure was brittle in all nature with fibre pull-out in the same direction which is an indication of low speed failure.  Specimens failed equally by matrix shear failure with constant debonding

Review Paper on Fabrication of Aluminum Magnesium Composite Material (Published)

This review paper represent the fabrication procedure of making aluminium magnesium composite material by use powder moddulory method.in this method we make this composite materil by doing recinforcement process.composite material is less in weight,high in strength,or also less coastly.composites have many different properties like high thermal conductivity,haigh tensile strength.composite material is generally an mixture of two or more same or different metlas.we can use composite metal in different mechanical sector,because of there multipurpose uses. In composite material we can easily find two metlas properties in one metal. . The new material may be preferred for many reasons. Composite materials are generally used for buildings, bridges, and structures such as boat hulls, swimming pool panels, race car bodies, shower stalls, bathtubs, storage tanks, imitation granite and culture marble sinks and countertops. The most advanced examples perform routinely on spacecraft and aircraft in demanding environments. Surface metal matrix composites (MMCs) are a group of modern engineered materials where the surface of the material is modified by dispersing secondary phase in the form of particles or fibers and the core of the material experience no change in chemical composition and structure.
